Schunk modular clamping blocks for precise serial production
1 min read
Schunk has reworked its series of Tandem clamping blocks to make them part of a modular system for highly efficient workpiece clamping suitable for a multitude of machine tools. The modular clamping system is compact but can develop enormous forces in confined spaces. The improved system is extremely flexible and can be actuated pneumatically, hydraulically, via spring force or manually.
The one-piece rigid base body, the wedge-hook kinematics and the ground jaw guidance provides concentrated clamping forces of up to 55 kN. The excellent repeat accuracy of 0.01 mm guarantees precision results. The Tandem clamping force blocks are suitable for sophisticated milling operations with high machining volumes, high cycle times and minimum tolerances. Due to the two integrated jaw interfaces, top jaws with tongue and groove, plus jaws with fine serration can also be used.
The optimised chip-deflecting outside contour and the minimum gap size prevents the penetration of swarf. Special fitting screws ensure that the unit can be repeatedly changed the Tandem clamping blocks can be lubricated via two lubrication nipples laterally, or from the bottom-sided connection. Even in the case of narrowly attached clamping solutions, lubrication channels and grooves evenly distribute grease over the entire guiding surfaces.
The clamping blocks are available with a standard stroke, long stroke or with a fixed jaw in sizes from 64 to 250 mm. The modular system has 30 standard clamping force blocks.
